DESCRIPTION

The side collision sensor RH circuit (to determine deployment of the front seat airbag assembly RH, curtain shield airbag assembly RH and front seat outer belt assembly RH) is composed of the airbag ECU assembly, side airbag sensor assembly RH, side No. 2 airbag sensor assembly RH, rear airbag sensor RH and No. 2 airbag sensor assembly.

The side airbag sensor assembly RH, side No. 2 airbag sensor assembly RH and rear airbag sensor RH detect impacts to the vehicle and send signals to the airbag ECU assembly to determine if the airbag should be deployed.

These DTCs are stored when a malfunction is detected for the side collision sensor RH circuit.
